PROBLEM TO BE SOLVED: To accurately determine the detoxification efficiency of a fluorescent gas by gas treatment devices at low cost by performing analysis of high precision by monitoring the detoxification efficiency in a plurality of the gas treatment devices under an actual use condition and excluding the effect of moisture and dust present in the gas in large quantities. SOLUTION: The monitor device of the gas treatment devices includes a plurality of the gas treatment devices 1A for subjecting the harmful component in an exhaust gas to detoxification treatment to discharge the same and leading out the exhaust gases before treatment as gases A to be measured and the gases after treatment as gases B to be measured, a first gas analyzer 3, a sampling device 2 for selectively sampling a kind of the gas from a plurality of the gases A to be measured or the gases B to be measured from a plurality of the gas treatment devices to supply the same to the first gas analyzer, a calibration gas supply device 4 for supplying the calibration gas for the first gas analyzer, a control part 5 for controlling the selective sampling of a plurality of the gases A to be measured and the gases B to be measured in the sampling device and an arithmetic part 6 for determining the detoxification efficiency in the gas treatment devices on the basis of the measured value from the gas analyzer.
